Hi, where you read the temps from, cpu core ? or CPU, i use CPUID hardware monitor, its got cpu core temps ?, using a Arctic extreme cooler is not very good at all, its idle is 40c on all cores, and loads 60c, can only get it to work on 3.7ghz without crashig in Intel Burn Test, just ordered a Scythe Mugen 2 and will try again, will be happy it to run 3.8ghz on stock voltage (which is 1.4v correct ?)
